GASKET.

Specification of Letters Patent.

Patented Aug'. 161, 1921.

Application led October 4, 1920. Serial No. 414,485.

To all whom t 'may 002i cerf/z.: Beit known that l, .losnrrr HoLLE, a citizen of the United States, residing at Newark,

'in the county of Essex and State of New Jersey, have invented new and useful Improvements in Gaskets, of which the following is a specification.

This invention relates to gaskets, and more particularly to gaskets of the kind disclosed in my copending application, Serial No. 319,274, filed August 22nd, 191.9. The gasket. disclosed therein is made of sheet metal Ashaped to provide two tubular guide flanges on opposite sides of an outwardly extending, annular section forming a chamber to receive and retain a ring of fibrous material, such as asbestos.

The object of the present invention is to reinforce or strengthen at least one of said tubular guide flanges against being bent inward or otherwise displaced when such lange"striles against the edge or' the hole or port in the part into which such flange is insert-ed in the application of the gasket in its position of use..

The invention consists further in the matters hereinafter described and, more particularly pointed out in the appended claims.

In the accompanying drawingsl Figure l is a side elevational view of a gasket embodying the features of my invention;

Fig. 2 is an enlarged dianietrical sectional view taken on line 2-2 ot Fig. 1; and

Fig. 3 is a. horizontal sectional view taken through that portion ot the wall of Van engine casting provided with the ports for the intake and exhaust manifolds, respectively, and showing gasketsof my invention between such parts at the joints thereof.

As shownin the drawings, the gasket is annular and has a body portion made/of sheet metal, such as copper, and formed to provide two tubular guide flanges l and 2, substantially in alinementand on'opposite sides of an outwardly extending annular section 3 forming an annular chamber to receive and retain a ring 4 otlibrous material, such as asbestos.

To reinforce or strengthen one of the tubular guide flanges so as to prevent it from being bent over or inward or otherwise. displaced out of its proper guiding position in the insertion of that' guide into a port hole or the like, I provide a reinforcing member Yend of the manifold.

made. of sheet metal and annular in form. Thishiember, in the form shown in the drawings, has two integral flanges 5 and 6, arranged substantially at rightangles to each other, and when applied to the gasket has its base flange 5 Vinserted into the cham ber formed by the sectiorl 3 between the fiber ring 4 and the adjacent wall ol the section The other flange 6 is substantially 1n alinement with the tubular guide l and extends away from the same across the inner edge of the ring Lt and along the inner surface of the tubular guide flange 2. The flange (i has a diameter Substantially equal to the inside diameter of the guide 2, so that the llange G has a tight fit against the guide 2 on the inside thereof. The height or length of the flange 6 is equal to that of the same dimension of' the guide f2 and the thickness of the ring 4, and the flange has its outer edge terminating at the outer edge of the guide 2. The flange (i is thus a part of the guide and makes it have a multiple thickness ol' sheet metal, with the result that l the guide 2 is strengthened to that extent. The flange 5 seating against a wall oithe section 3 and hcld in contact therewith by the fiber ring 4, prevents the flange 6 from being bent inwardly and thus supports the guide ange 2 and prevents it from being bent inward. This, therefore, supports the guide flange 2 in proper guiding' position and prevents it from being bent inward on striking against the port into which it is inserted. Moreover, the outeredge of the guide flange i2 being formed of a multiple thickness of metal prevents curling or bending over of that edge.

In Fig. 3,1 have shown an intake manifold] and an exhaust manifold 8, these registering with the ports 9 and '10, respectively, in the wall l1 of the engine casing, when the manifolds are in use and clamped against said wall. The gasket shown and described is used at the `ioint between each manifold and its cylinder port. When applying the manifold against the cylinder' wall, a gasket is firstapplied to the manifold before it is applied to the engine. In applying the gasketfits tubular guide flange 1 is inserted into the open end of the manifold until stopped by the section 3 contacting with the gasket with the manifold, or, in other words, the m..nit`old carries the gasket. The mani- This connects the l f the flange is likely to strike the edge of the port or against the wall lly about the port, and, being reinforced or strengthened by the flange 6,tlie guide flange 2 is prevented from being bent inward or otherwise displaced on i striking such parts. Manifestly, the use oit the gasket isnot 'limited to one application; tliatis, the guide flange 2 is held against bending and thus is maintained in proper condition and enables the gasket to be used over and over again and thus does not have to be thrown. away after one installation.

VThe body of the gasket, as shown herein, follows tlie construction in my copending application; that is, the tubular guide flanges l and 2 are made separate with the guide 'l having an integral flange bent outward and inward to form a chamber for the liber ring l, and the other guide flange 2 having an integral fiange bent outward to extend under the adjacent wall of the chamber, as shown in Fig. 2, although of course I do not wish to be limited in my present invention to this exact formation ci gaske Furthermore, the reinforcing member o't' my present invention may be variously changed and modiiied without departing from the spirit and scope of my invention.

I claim as my invention:

l. A gasket of the character described,

igasnefia comprising a. metallic body portion. formed -to provide two tubular guide tianges extend-- ing' in opposite directions on opposite sides vof-an outwardly extending annular section ring of fibrous material, and-a metallic annular member .inside ot one of said guide flanges and littiiig against the to bold said flange against bending inward.

3. A gasket of the character described,

comprising av metallic body portion formed to provide two tubular guide flanges extend ing in opposite directions on. opposite sides of an outwardly extending annular section forming a chamber to receive and retain a ring of fibrous material, and a strengthening member inside of one of said guide iianges and haring two iianges, one extendingq into said chamber under the ring thereon and tlie other extending across the inner edge of the ring' and fitting against tliev inside of the last mentioned guide Harige.

lin testimony that i claim the foregoing); as my invention9 I aliix my signature this 27th day of September, A. il. 1920.
